new and useful ulinprovemente in Looking- Chains, of which the following ie e elettr, tnll, and exn'et description.

The object of this invention is to provide a -ehein for looking e. movable part or object to a. stationery port or relatively stationery port by ineens ot n. ehein. in enen n. manner that all stress and eti-nin that may be ex.-

v erted upon the niovoble port to noo've it evvny from the relatively stationery port, will be leken up entirely by the chain links, ond :not bythe lock mechanism, as is the ense :rtpreeent when ordinary pod locks are used to conneet .the tree ends ol." chaine, when such are used tor eeenriiig purposes. y

My invention is epplieeble, es will be en purent to e great divereity ol" rises.-

rlhe chaining of n Wagon Wheel to the wagon body, of en nntornobile Wheel tothe chassis, are tvvo apparent uses of themnltitude of instances Where my invention may be used. I

ln carrying ont rny invention l provide e. oontirnione elmin oit" linke, preferably of the ordinary chain eonetrnetion, end l' eenneet the two free end links oit this1 chain with :in open link, that ie, :i linl; having en opening on one of its Sides to permit the free ent e ot the ehnin to be hooked to seid open link. loneeqnently n dirent poll on the ebnin will be teken np by the Streight unopened eide of the open link" which is preferably made stronger' than the ordinary links of the chain. Alletrziin :troni the movingl port is thus transmitted :from the ordinary ehoin links to the solid eide member of the open link. Carried by the open linlt, end inovable thereon. l provide n look provided with V ineens to permit it to be moved into poeition to noyer the openii'ig; in the eide of the open linie This look may be of nny Suitable con? struction. ln the dre-Wings appended hereto, it is shown :1e en ordinary 'tumbler lock, in. which the tnrnlolere ore moved into the path oit tbe'open eide oi? the link to prevent the Seine trein being; dieelosed outside ot the lt 4will time be neen` that :no strnin or nll on the linlc. een in. only wey be trzinsini l` to the lool( inea/iranien). to diernpt and tend to destroy the Sonie.

ln the neeonnoonying drowinge, .Figure l ie n perspective view oli e portion ot the' chain and loeli with one side of the easing removed. Fig. 2 is n plain View ofthe one link, sind lock, with theoover ot the easing removed. Fig. 3 is :L view Similar to Fig. 2, but showing:l the link in open positionu Fig; 4E ie n. eroee Section on line 4wd@ Fig. 2, Fig.

.5 is detztil ot one end of the tumbler, and

portion oli f1. Wagon, showing my invention in plone.

its shown in the drawings, the chain may be composed of e number of ordinary o A)en linlge l, which may be passed around. e wagon wheel 2, one part of the chain in this etree, the open link 3 being secured to the stationery body l of the Wegen by e sorevveye 5, although any other link' of the chain nifty be secured `to the Wagon. The open link is provided with one strong straight side terminnting'in ordinary looped ende 7, which may loe given en additional curve outward 'from the Center ol. the link to eid in securing n line ot' draft nearly eentrally with thie eide of the link. rlClie other side oli' tbe link is composed. of two short meub bere with o Space between the saine. The member d Slnbbed :it its end 9, to lit 'the openingl in certain turnblere to be hereinotter described, while the end l0 is adopted to enter :r hole in the lock canning when the devine is 'in :i look position, there beingf Snlicient epnee between the endet the eide 110 und the eneing to permit the entr-nee of n chain linlr Ill. A. linlt l2 is preferably ,always secured. to the opposite end oli the open. link. f

` A easing composed of two halves 13 und V14, is provided, which is ndnpted to be slid no sind down the open. linlr. A spring l5 bearing; against the lnner flange oit the eee ing, and n pin lo on the side d, of the open link, tends always to keep the link in boeition oit Fig. Tn'mblers l? mounted on er post lf3 and provided with lend springe lll bearing;V zeggeinety the Stud E20 in the easing, nre held by their springs normally in the punition of l? 2. A key poet 2l is pro vided, tlint e lrey 2Q moy be inserted. into the ion lrey poet to torn the tnniblere into the poet tion oli Fig, 3, in which ense n spring lli will nrojeetithe open end lt) the open linlr` ontwnrd into the posit-ion ont Fig. 3, that one end oit o ehein. tney he hootzed thereto.
